ENERGY CONSERVATION OF THE AIR-CONDITIONING SYSTEM OF HOTELS BUILDING IN MAKASSAR CITY

Available of hotel building in Makassar is supported by the climate condition which wet tropical climate. The rain season which significant as part of moth in a year. The dry season which sufficient compare with rain season. The function of building envelope in external of hotel building architecture appointment of energy conservation criteria which become comparison in design process of hotel building, particularly include the exterior field design in relation with the building performance. That cause require of method to be less of external load such as suitable with Indonesia National Standardization in appoitnment of criteria about building envelope design which stated in Overall Thermal Transfer Value – OTTV < 45 Watt/m2 .The research approach are mix between qualitative and quantitative methods. Location of research in Makassar City, with reason the researcher stay there and observed of rise the hotel building which to be interested related with energy conservation system of air to see the saving energy and thermal comfort of hotel building. Data analyzed in qualitative descriptive, analyzed of building envelope, cooling load and thermal comfort. The result of research found the energy conservation system of air have used on five hotel building which showed the energy from AC in the room which effected of OTTV. Analyzed of conservation control energy saving from air-conditioning system from the hotel building appointment by cooling weight analysis in internal or external.
